2020 Mercedes-Benz GLC 300 AMG Line Prem + D 4M A 1.9L Diesel · E3 GER

The vehicle is currently roadworthy following a PASS on 30 September 2025 at 27,302 miles, but the maintenance trend shows a concerning deterioration in tyre condition over time. The most recent test reveals multiple tyre defects, including a deep cut on the nearside front tyre and a worn-offside front tyre approaching the legal limit, both of which are serious safety risks. This follows a pattern of repeated failures related to tyre integrity, with cuts penetrating the ply layer appearing in successive tests from 2024 onwards—indicating either poor tyre selection, inadequate rotation practices, or underlying alignment issues that have not been addressed. The recorded mileage of 27,302 miles at age six years equates to an average of just under 4,600 miles per year, which is significantly lower than typical usage for this model. However, the gap between the 2024-10-10 test (22,385 miles) and the 2023-09-04 test (15,804 miles) suggests a sudden jump of over 6,500 miles in less than a year, raising questions about whether the vehicle was driven infrequently or stored for extended periods. The clean PASS in October 2024 at 2,385 miles appears inconsistent with the prior mileage and may indicate a data entry error or misrecorded odometer reading, as it contradicts the subsequent high-mileage progression. Given the recurring tyre damage—particularly deep cuts reaching the ply layer across multiple corners—the buyer should conduct a thorough inspection of the suspension system, wheel alignment, and steering components. Binding or misaligned wheels can cause uneven wear and increase the risk of punctures or tread separation. The brake system should also be examined closely, especially the nearside front caliper and disc, as persistent tyre issues often correlate with braking inefficiencies. Additionally, a structural check for corrosion, particularly around wheel arches and underbody panels, is advised, as long periods of inactivity combined with moisture exposure can accelerate rust development in otherwise low-mileage vehicles.
